[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an intermittent transfer device for suspending a work on a rail and transferring it intermittently.

[0002]

2. Description of the Related Art Conventionally, as an intermittent transfer device of this type,
For example, there is one disclosed in Japanese Patent Laid-Open No. 1-294416. As shown in FIGS. 9 and 10, this conventional intermittent transfer device rotates the drive shaft 1 forward and backward at a predetermined angle to rotate the rotating arm 2, the pressing roller 3, the receiving plate 4, the operating shaft 5, and the like. Then, the comb tooth body 7 is moved in a rectangular shape via the operation arm 6, and the container 9 suspended by the rail 8 is intermittently conveyed.

[0003]

However, the structure of the conventional intermittent transfer device is complicated, and the manufacture of the device is complicated and not easy. Further, as a conventional intermittent transfer device, a screw conveyor for transferring a container as a work by intermittently rotationally driving a screw shaft formed by engraving a spiral groove on a rotary shaft is known. It is difficult for the screw conveyor to stop the container at a predetermined position, and when the transport distance is long, the screw shaft becomes expensive and the manufacturing cost of the apparatus becomes high.

The present invention has been made by paying attention to the problems of such a conventional intermittent transfer device. The structure is simple, there are few failures, the manufacturing cost is low, and the transfer device can be easily moved to a predetermined position during transfer. The purpose is to provide an intermittent transfer device that can be stopped at any time.

[0005]

In order to achieve the above object, the present invention provides a pair of rails horizontally arranged in parallel with each other, and a workpiece suspended from a flange portion provided around the outer periphery of an upper portion of a main body portion. In an intermittent transport device that intermittently transports a predetermined distance along the rail, in the horizontal plane below the rail, it extends in the front-rear direction along the rail and is formed by connecting a number of substantially triangular blade pieces. The thrust member on the left side with respect to the front-rear direction having the corrugated blade portion and the position opposite to the blade portion of the thrust member on the left side have a shape symmetrical with the thrust member on the left side and the thrust on the left side. A pair of thrust members formed of a thrust member on the right side with respect to the front-rear direction formed by shifting the position of the blade piece of the member by less than 1 pitch in the front-rear direction; Part in the horizontal plane The left drive means for reciprocating the left thrust member with a predetermined stroke so as to cross the rail at right angles and the right thrust member are symmetrical with the stroke of the left thrust member about the rail. And a pair of driving means composed of right-side driving means for reciprocating, the left-side thrust member and the right-side thrust member are alternately reciprocated.

Further, according to the present invention, there is provided a carrying-in means formed by connecting a pair of rails having the same sectional shape as the pair of rails and inclined forward and downward at a predetermined angle to the rear ends of the pair of rails. I decided to prepare.

[0007]

For example, the blade portion of the second thrust member is arranged in front of the blade portion of the first thrust member by less than 1 pitch, and the first blade portion is railed by the rail. When the work is supplied to the carry-in port of the conveying means in a state where the work is moved to the left outside of the gap and the second blade portion is moved to the position across the gap of the rail, first, the second drive is performed. By the operation of the means, the second blade portion retracts to the right by one stroke and stops at a position outside the rail gap. Then, the first driving means operates to move the first blade portion across the gap between the rails to the right for one stroke and stop at a predetermined position. At this time,
The work is pushed by the inclined part of the blade of the first blade and advances along the rail by a distance shorter than one pitch and stops.
Then, the first driving means operates to move the first blade portion back one stroke to the left and stop at the position where the first blade portion is outside the left side of the rail gap. Then, the second drive means is actuated to move the second blade portion leftward by one stroke and stop at the position where it crosses the rail gap. At this time, the work is pushed by the inclined portion of the blade piece of the second blade portion, advances along the rail by a distance shorter than one pitch, and stops. Hereinafter, in the same manner, the pair of thrust members are alternately reciprocated by one stroke to stop the work along the rails of the conveying means for a predetermined distance by one pitch, and intermittently in front of the rails of the conveying means. Can be transported.

Further, when the carrying-in means is provided, the frontmost work of the many works suspended on the rail of the carrying-in means is
When it slides down naturally on the rail of the carrying-in means and is supplied to the carry-in entrance of the carrying means, a pair of thrust members of the carrying means actuate to move the frontmost work forward by one pitch along the rail of the carrying means. At this time, the work following the frontmost work is naturally slid down on the rail of the carry-in means and supplied to the carry-in entrance of the carrying means. In the same manner, when the work at the carry-in entrance of the carrying means is carried forward by one pitch, the works at the rails of the carry-in means are automatically supplied one after another to the carry-in entrance of the carrying means.
